SPECIFICATION forming part of Letters Patent No. 669,511, dated March 12, 1901.

Application filed July 16, 1900.

To all whom it may concern.-

Be it known that we,RAYMOND V.DAHIS and FREDRIOK A. DAHIS, citizens of the United States,residingin the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Puzzle Devices, of which the following is a full, clear, and exact description, reference being hadto the accompanying drawings,of which- Figure 1 is a plan view. Fig. 2 is a section on line m 00, Fig. 1.

This invention comprises a box or receptacle with a plane bottom having one or more spots or marks thereon at predetermined points, in which box is contained a ball-magnet and a plate or plates of iron or other metal capable of being attracted by said magnet. The thing to be done or the problem to be solved 'is to cause the ball by suitable manipulation of the box to come into contact with the said plate and then carry it (the plate) over the spot and deposit it thereon, or if there be several of the plates (in which case there will be a corresponding number of the spots) to perform like operations to deposit a plate upon each of the spots, all as hereinafter particularly described.

Referring to the accompanying drawings, which represent a preferred form of the invention, 1 is a box, preferably of the cylindrical form shown, upon the inner side of the plane bottom of which are equidistant spots or disks 2. (Seen in Fig. 1.)

3 is a magnet of spherical form.

4 represents small loose plates of thin sheetiron, corresponding in number to that of the spots 2, and of any desired form such, for example, as a conventional star, as shown. The ball and plates are contained within the box, and in order to retain the same permanently therein we usually secure to the box a cover 1 of glass or other suitable transparent material.

The manner of operating the device is as follows: The box as it is held in the hand is tipped slightly from the horizontal position in order to cause the ball-magnet to roll in the direction required to bring it into contact with one of the plates 4, which latter will then be held to the ball by magnetic attraction.

Serial No- 23,844. (No model.)

The box is now so manipulated with relation to the horizontal plane as to cause the ball to roll toward the particular one of the spots desired and to carry with it the plate until the latter is brought immediately over the spot, whereupon bya slight quick horizontal movement of the box the ball may, if the operation be deftly done, be made to detach itself from the plate, leaving it (the plate) upon the spot, this being the ultimate object of the device; or the ball may when the plate has been brought over the spot, as before described, be rolled over upon the plate, thus breaking the connection between the plate and the magnetic pole of the ball owing to the weight of the ball upon the plate. Although it is not easy to thus cause the plate to be lodged upon the spot, it can be done by nice or skilful manipulation of the box. As the contact of the ball and plate is at a point only, and so the adherence of the plate to the ball is but slight, the ball will readily roll and yet carry with it the plate, and the latter may readiiy be detached from the ball by suitable manipulation of the box, as before mentioned. When a plate has been deposited upon each of the spots respectively,as indicated by dotted lines in Fig. 1, the puzzle has been solved.

We sometimes make the spots of different colors and the plates of corresponding colors, in which case the thing to be done is to bring each plate upon the spot of its color.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- The hereinbefore-described puzzle device, comprising the box having the spot or spots on the bottom thereof, the ball-magnet, and the plate or plates, capable of being attracted by said ball, substantially as and for the purpose set forth.

In testimony whereof we have hereunto affixed our signatures this 9th day of July, A. D. 1900.
